    The acquisition of agricultural land is a crucial aspect of survival for numerous rural communities, serving as a fundamental tool for combating poverty and food insecurity and promoting equitable sustainable economic progress. The expropriation of land offers a promising prospect for remedying past inequities and promoting both economic progress and food sufficiency. Limited research has examined the association between land expropriation and food security, livelihood shocks, and the well-being of rural households worldwide. Therefore, this research explores the implications of land expropriation on food security, livelihood shocks, and well-being of land lost rural communities. The data were collected from 384 farmers selected through stratified sampling techniques using face-to-face surveys in rural China. The data were analyzed using descriptive and logit regression models. The descriptive findings showed that land expropriation has detrimental effects on the livelihood, food security, and well-being of the farmers. Furthermore, these impacts are more harmful among land-expropriated households with a lower educational level, a large family size, and women farmers in less developed rural communities. The econometric results evinced that gender, age, education level, marital status, family size, and negative changes in income all significantly affect the impact of land expropriation on the food security of farmers. Similarly, the findings revealed that farmers with lower education levels were more likely to be affected by land loss as compared to farmers with medium and high education levels. Farmers with complete land loss were 1.70 times more likely to suffer livelihood shocks than those with partial land loss. The results also evinced that the well-being of all farmers was not affected equally, and some farmers’ well-being was affected more than others due to various socioeconomic backgrounds. Therefore, this study suggests the implementation of public policies that provide support to farmers who have been marginalized due to land acquisition.</div

    Water pollution is growing at an alarming rate, particularly due to the colored waste- water released by the various industries into aquifers and fresh water sources, and in some extreme cases, they have reached the water table. Faisalabad, a city in Pakistan where there is an industrial cluster of textiles dyeing and manufacturers, water table has become undrinkable. The presence of hazardous dyes and chemicals imposes serious health issues on humans, animals, and plants. The treatment of such toxic dye effluents is crucial and could be done by efficient degradation methods such as photocatalysis. The current study presents synthesis of poly(o-methylaniline)/zinc oxide/reduced graphene oxide nanocomposite (POMA/ZnO/rGO NC) using a chemi- cal oxidative polymerization process and explores its properties as a photocatalyst by demonstrating degradation of three dyes. The composite was characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), photoluminescence emission spectroscopy (PL), Brunauer Emmett–Teller analysis (BET), and UV–visible spectroscopy (UV–visible). Further, the photocatalytic activity of POMA/ZnO/rGO NC was evaluated and compared by degrading the direct yellow 12 (DY 12), congo red (CR), and malachite green (MG) dyes in aqueous media under UV irradiation. The results indicated that after 110 min, POMA/ZnO/rGO composite degraded the dyes by 92% (DY 12), 86.1% (CR), and 82.1% (MG), respectively. Moreover, kinetic studies of the photocatalyst were also performed along with reusability test, total organic carbon, chemical oxygen demand, and degradation mechanism

    Women LIS researchers in Pakistan have been publishing their research since 1977. This paper provides a bibliometric analysis of the 43 years (1977–2020) of their research. This study conducted a bibliometric analysis of the data collected from four data sources, the Web of Science Core Collection, Scopus, LISA, and LISTA, to include the maximum number of scholarly publications by women Pakistani LIS researchers working in Pakistan or abroad. The study findings highlighted an upward trend in publications since 1977. It appears to have gathered momentum after the year 2003. The University of the Punjab was the top-ranked organization in publishing research by woman LIS researchers, and the Department of Information Management at the University of the Punjab was identified as being the most prolific in this regard. The researchers had published over 40% of their research in national journals and the rest in international journals of good repute. Kanwal Ameen led the list of woman researchers with over 100 research publications to her name. The main areas of research were academic libraries, information literacy, and evolving trends in LIS. This is the first research paper highlighting the different dimensions of Pakistani LIS women researchers since they started publishing in 1977. The findings of the study would help future researchers to understand trends and various bibliometric aspects of publications originating from women LIS researchers in Pakistan. The findings could also help LIS researchers and funding organizations in promoting the profession. </p

    Cadmium (Cd) is a noxious and non-biodegradable heavy metal which instigates various organ toxicities such as cardiac injuries. Pinostrobin (PSB) is a potent dietary bioflavonoid, which shows various pharmacological potentials. The current research was designed to evaluate the ameliorative effects of PSB against Cd elicited cardiac dysfunction in rats. Twenty-four albino rats were apportioned into four equal groups viz. control, Cd (5 mg/kg), Cd (5 mg/kg) + PSB (40 mg/kg) and PSB (40 mg/kg) only treated group. It was observed that Cd intoxication reduced catalase (CAT), glutathione reductase (GSR), superoxide dismutase (SOD), glutathione peroxidase (GPx), activities and glutathione S-transferase (GST) contents while escalating the levels of reactive oxygen species (ROS), hydrogen peroxide (H2O2) and malondialdehyde (MDA). Furthermore, Cd exposure escalated the levels of cardiac injury markers such as creatine phosphokinase (CPK), creatine kinase-myocardial band (CK-MB), troponin I and lactate dehydrogenase (LDH). Besides, the levels of inflammatory cytokines nuclear factor- κB (NF-κB), interleukin 1beta (IL-1ß), tumor necrosis factor- α (TNF-α), interleukin-6 (IL-6) levels and cyclooxygenase-2 (COX-2) activity were upregulated in Cd intoxicated group. Similarly, Caspase-3, Bax and Caspase-9 levels were augmented, and Bcl-2 levels were reduced after Cd administration. In addition, the histopathological examination revealed a notable cardiac tissue impairment in the Cd exposed group. Nonetheless, PSB treatment significantly (p < 0.05) recovered the abovementioned Cd-induced impairments. Therefore, the current study revealed that PSB might be a promising ameliorative agent to ameliorate Cd instigated cardiac damages

    Drought is a misfortune for crops. Wheat is a staple crop and its sustainability and adequate supply are vital to food security around the world. The development of drought-tolerant cultivars in wheat is a major challenge to breeders, therefore there is dire need of time to determine the genetic components of drought tolerance in wheat crop. To overcome intense drought stress, wheat plants undergo certain morphological and physiological changes and develop certain genetically adaptive mechanisms. Since wheat is an allotriploid with three sub-genomes, its adaptability molecular mechanisms to drought, particularly needs scientific attention. Here, we systematically and comprehensively reviewed the causes of wheat drought tolerance and the consequences for wheat physiology and genetics. The quantitative trait loci (QTL), which be function on the control of wheat drought tolerance, were comprehensively summarized by a meta-analysis and total 75 meta-QTLs (MQTLs) were identified. In addition, we summarized the genes tightly involved in wheat drought tolerance, and several important genes were selected to elucidate signaling networks related to the wheat drought tolerance. This review is integral to growing suitable strains in the worldwide arid regions to improve wheat yields under recent global climate change scenarios
